Solved: easy help, advice for type of External HD case

this should be a easy solve. I sorta figured out what type of external HD case I need. But I would perfer to check with you guys before I buy. Dont want to spend money then find out I got the wrong type of external hd case.

What I need to know what type of external HD case should I search for? like sata, IDE, 3.5, 2.5", etc?

few weeks ago I bought a WD Live TV for $5.00 with no power cable and remote at a thrift shop in town. then spent $15.00 for those missing items. My PC has the extra WD 200bg HD I dont use and would love to use it instead of speidng extra money for another external HD.

They do not. They get hot and life is shortened.
An external drive is not designed for continuous duty ie running 24/7 unless it has a fan. Some enclosures do have cooling fans however none support the old ide interface. Here is an example of an enclosure designed for hard use.http://www.newegg.com/Product/Product.aspx?Item=N82E16817173043

Most people use an external drive for image backups, file backups, etc. If you are going to attempt to stream media from this drive, I would just get an internal drive; more reliable and faster.

Im using a WD Live TV media player has two usb ports forUSB sticks or external USB HDs and can also stream. I will look into a fan case, but probably wont use it much, just to watch movies from time to time.
thanks so much for the help and details.
